Hello, I'm an Educator for Outpatient facility coding and need some feedback on interpreting POO guideline ch 20.b ...POO is assigned only once, at the initial encounter for treatment... We code for ambulatory surgeries, for example orif CPT 25545 of fx S52.571A; while playing soccer W21.02XA, on a soccer field Y92.322 (as documented in H&P from the day prior to surgery). The injury occurred 4 days prior and now presents for treatment/ surgery. One point of view is 7th character A means initial encounter and Y92.322 would be reported. Another point of view is this is not the initial encounter and Y92.322 would not be reported. I anyone would comment on if Y92.-- would be reported or not, I would appreciate it. thank you.
